What is "barachum"

Barachum is a representative of the Korean Buddhist ritual dance, ( jakbeop), and is performed by Buddhist monks with bara ( hangul:바라). The term bara describes a cymbal-like Korean instrument made with brass. The dance is composed of splendid and complicated movements among the jakbeop. Performers playing bara repeatedly step back and forth or revolve in agile action. The purpose of barachum is to expel evil spirits and to purify the mind.
